Its smaller branches form a regular herring bone pattern. Its trunk may achieve a diameter of 2m. Its brown/ red bark becomes grey with age and split into plates by vertical and horizontal fissures. Its monoecious flowers are inconspicuous and give rise to 30 or 40 stamens. Its bright green fruit appear at the base of each leaf and are up to 8mm long.
